New Features

Generalize make_local_cacher to take custom functions for saving, getting,
checking and deleting data.
Add crunch function to cache all values over a given size that are stored
in memory.
Add loop function
Add tag field to Rmonad objects and access functions:
- tag - set the tags of the current head node (or nodes at given indices)
- view - set the head of the graph to the given tagged node
- views - get list of Rmonad objects matching a given tag
- viewID - like view but with ID
- viewIDs - like views but with ID
- get_tag - get tags for nodes
- has_tag - check whether nodes have tags
- add tag argument to as_monad to allow tag setting at creation
- add tag argument to get_* to allow access by tag
- add tag to caching functions, to allow tag and cache to be set together
- give names to elements of lists returned by tag from get_* functions

Node names are now reproducible. If you notice any internal nodes
disappearing, please file a bug report, since this means we missed some case
in our hashing system.
Use saveRDS, rather than save, for local caching
Change print.Rmonad parameter print_value to value
Combine (and funnel) now stores failing inputs as NULL and does not delete
the failing parent's cache
In combine/funnel, tagged parents are not deleted

Add automatic caching, if a function takes a long time to run, it is cached
Add option to turn toggle auto caching: rmonad.auto_cache (default = FALSE)
Add option to set how long an expression can take before its result will be
cached: rmonad.cache_maxtime (default = 3 seconds)
Add option to set cache directory: rmonad.cache_dir (default = "cache")
Add option to set cache function: rmonad.cacher (default = make_cacher())

Fix expression capture in as_monad
Make index the second positional argument of has_value, as with other
accessors
Metadata lists are now evaluated in the natural lexical scope, with access
to the function arguments and variables in the scope where the function was
defined.

This is a major new release. It is mostly backwards incompatible with v0.3.0. Here are the main high-level changes:

The underlying graph model now uses igraph
The old oddly named ms_* vectorized accessor functions have been replaced with get_*.
The old m_* non-vectorized accessors have been removed (they are just a special case of get_*)
New has_* vectorized functions can be used in tandem with get_* to subset Rmonad attributes
Values can now be cached as local files, in memory, or however you like. The cache system of a specific node can be set by piping it into a "recacher" function.
Many forms of node post-processing can now be set in the node metadata. These allow automatic data summary generation; reformatting of captured errors, warnings, and messages; cache setting; and logging.
